We did our little cart ourselves (it was licensed as a mobile kitchen while we were in TX). It's a little on the "plain" side.
Nice thing is when we decide to do something else, we can remodel it (yet again) to suit our new whatever. I've been reading Roadfood (Pro section) for a long time now and I do not like the direction Food Vending seems to be heading. So I'm researching other possibilities. Food Vending is getting to be an expensive PITA.
